Hey, guys. I've recently spent some time collecting headphones data from manufactures' official websites and made a database. It contains almost every non-electrostatic over-ear model from every major headphone manufacturers I know.

I also collected some data from Audio Science Review's measurements. Thanks for amirm's work and authorization!

These are quite useful for evaluating how hard a headphone is to drive! I used to write an article named Conversion Relation between Sensitivities and Impedance of Headphones. With this theoretical basis, I'm able to write a python program to provide a method to analysis these data.

And these are some of my analysis results. I only selected some of the results that might interest you, but you can also customize the content you need. This data analysis tool supports a variety of customization options. Just provide parameters to the functions and it'll plot what you needed. (Don't get surprised that one product may appear twice in the table. Some of them is from ASR measurements and some is from official data)

You can find the tool and database and something else that might be useful in Sha1rholder/Sound-Library - GitHub. It's a non-profit project purely driven by hobby. Click Star if it helps, I'm grateful. If you are too lazy to visit GitHub, here's also an out-of-the-box analysis package including data and a tutorial.
